Key result
Combined percutaneous transluminal coronary angioplasty without stenting and subsequent surgical excision successfully treated a 77-year-old woman with an atypically located left atrial myxoma and acute myocardial infarction.
Case Report (n=1)
This case highlights the rare presentation of a left atrial myxoma causing acute myocardial infarction via coronary embolism and severe pulmonary hypertension, successfully managed with a combined percutaneous and surgical approach.
May support hybrid management in rare myxoma-related MI; leaves open need for prospective validation.
Myxomas are the most frequently seen benign cardiac tumor. They mostly originate from interatrial septum. They can lead variable signs and symptoms. Opposite to their benign structure, embolic and obstructive complications can be fatal. Myxomas can rarely lead acute myocardial infarction due to coronary embolism. In this article, we presented a left atrial myxoma case that originated from posterior mitral annulus with simultaneous acute inferoposterior myocardial infarction, severe pulmonary hypertension and dynamic mitral stenosis. The patient was managed with successful percutaneous transluminal coronary angioplasty of the left circumflex artery without stenting and surgical removal of the myxoma consecutively. Pulmonary hypertension dropped significantly in postoperative follow-up.

Demir et al. (2016) conducted a case report in Left atrial myxoma with acute myocardial infarction and severe pulmonary hypertension (n=1). Percutaneous transluminal coronary angioplasty (PTCA) without stenting followed by surgical excision was evaluated on Clinical recovery and reduction in pulmonary artery systolic pressure. Combined percutaneous transluminal coronary angioplasty without stenting and subsequent surgical excision successfully treated a 77-year-old woman with an atypically located left atrial myxoma and acute myocardial infarction.
